Bismuth shot hits like lead shot, but won't harm barrels and chokes, which means that it is ideal for use as a non-toxic shot in fine double-barrel shotguns, smallbore shotguns and any other shotguns with fixed chokes. Care and proper loading techniques must be observed in order to load bismuth shot effectively.
USFWS-approved non-toxic, beautifully consistent, dense, and it will be drop-dead lethal in your loads.
Overall Pellet Softness: Bismuth is the softest metal of all available non-toxic shot types. Bismuth is much softer than any barrel iron and steel shotgun barrels. Therefore it is the non-toxic shot that is easiest on your fine shotgun.
